POLARIS is technological facility currently under re-labellisation procedure by AMU and CNRS.
The facility offers a wide panel of technological services and expertise in optical fabrication and optical metrology. We have the capability to manufacture aspherical optical mirrors with diameters up to 1200mm with the stressed-mirror polishing technique developed at LAM since the 1960s.
The facility possess a wide range of state-of-art equipements for the metrology of optical components and systems: interferometry, wavefront sensing, profilometry, microscopy, rugosimetry, spectrophotometry, goniophotometry, photometry.
The facility alos develops and maintains expertise in structural gluing (mechanical and/or optical).
The objective of POLARIS is two-fold: supporting the LAM instrumental projects for ground and space missions; supporting external clients (both institutional and industrial).
